Probably - if you had 134 TCP connections opened before :-)
They should disappear after a few minutes (2*"maximum segment lifetime"~4min).

To quote RFC 793 "Transmission Control Protocol.":
    TIME-WAIT - represents waiting for enough time to pass to be sure
    the remote TCP received the acknowledgment of its connection
    termination request.

NB: On NetBSD 1.3 I usually had some "zombie" connections wich were stuck
in *_WAIT stages forever.
